   Disposition of Comments Report for ISO/IEC DIS 14519 - Information
     technology - POSIX Ada Language Interfaces - Binding for System
        Application Program Interface (API) - Realtime Extensions
                  (Revision of ISO/IEC 14519-1:1994)


Four comments were received, and are recorded below, together with
the disposition.

Comment from France:

| AFNOR votes NO to ISO/IEC DIS 14519.
| AFNOR will reverse its vote if the comment on the French title is
| adopted.

| Proposed change:
| Change the French title for the following:
|
| Technologies de l'Information - Interfaces POSIX pour le language
| Ada - Couplage avec l'Interface de programmation syste\me (API) -
| Extensions temps r/eel.

Disposition:

This change is accepted in principle.  However, in view of the
proposed change to the English title (below) to reflect the fact
that the document contains more than the real-time extensions, a
representative of AFNOR was invited to make a corresponding change
to the proposed French title.  The result is the following, which
we propose to use:

"Technologies de l'Information - Interfaces POSIX pour le language
Ada - Couplage avec l'Interface de programmation syste\me (API)
Incluant les extensions temps re/el"

Comment from the UK:

| The UK advises that the WG15/IEEE synchronization plan should be
| closely followed to ensure that the correct drafts are used.

Disposition:

The balloted DIS is identical to the final published IEEE and
ANSI standard.

Comment from the USA:

| The USNB believes that a more appropriate (English) Title for this
| document when it is published as ISO/IEC 14519 would be as follows:
|
| POSIX Ada Language Interfaces - Binding for System Application
| Interfaces (API) including Realtime Extensions.

Disposition:

This comment is accepted.  The document forwarded to ITTF for
publication will contain the text of the IEEE/ANSI Standard, with
the title modified as above.

Comment from Canada:

| On Ada bindings, no, as this does not meet our international
| requirements.  It incorporates rather than references another
| existing standard ("thick" binding vs. "thin" binding) without
| demonstrating how synchronization is to be maintained, and it
| lacks market relevance.)

Disposition:

This comment does not permit any resolution. However, the
following responses are provided for the record.

Regarding Canada's international requirements: since those are not
stated no response is possible.

Regarding the thick vs. thin binding issue: that was settled long
before this revision, in 1994, when the original 14519 was
approved; the issue was debated extensively within ISO WG15 and
IEEE PASC balloting group, and there was a persistent strong
consensus for the thick binding approach; this consensus was later
strengthened by the lack of progress on POSIX language-independent
specifications. 

Regarding synchronization: how the standard will be maintained is
well demonstrated by the existence of the current revision, which
brings the Ada binding fully into synchronization with the
ISO-approved C-language bindings for POSIX, and by the POSIX.5c
standard which is in IEEE ballot.

Regarding market relevance: the Ada market is small, but
persistent; the portability and reliability that come from strong
standardization are among Ada's selling points to that market;
even in Canada, Ada and POSIX are reputed to be used together for
air traffic control.
